fix(providers): use DB name for ClaudeCLI, ACP, and Anthropic registration

Provider Name() methods returned hardcoded strings, so DB-registered
providers with custom names got wrong registry key — causing "provider
not found" fallback. Add WithClaudeCLIName/WithACPName/WithAnthropicName
options, pass p.Name from DB registration paths. Config-based paths
keep hardcoded defaults.

Closes #742
